[dpdk-dev] [PATCH v3 02/28] ethdev: Remove assumption that port will not be detached
Tetsuya Mukawa
mukawa at igel.co.jp
Tue Dec 9 07:30:03 CET 2014
To remove assumption, do like followings.
- Add 'attached' member to rte_eth_dev structure.
This member is used for indicating the port is attached, or not.
- Add rte_eth_dev_allocate_new_port().
This function is used for allocating new port.
